Description
The RMPA1902-58 is a monolithic high efficiency power amplifier for PCS CDMA personal communication system applications. The MMIC requires off-chip matching. The amplifier circuit design is a single ended configuration that utilizes harmonic tuning for increased power added efficiency and linearity. The device uses Raytheon’s Pseudomorphic High Electron Mobility Transistor (pHEMT) process.

FEATUREs
◆ Positive supply voltage of 3.5 V, nominal
◆ Efficiency of 36%, typical, for CDMA average power out of 29 dBm
◆ Small outline quad package
